FIELD OF THE INVENTION

An embodiment of the present invention relates to a lawn repair devicespecifically for repairing divots created by golfers.

BACKGROUND OF THE INVENTION

Divot repair devices have been described by Spring's U.S. Pat. No.6,637,355 that allows the distribution of sand and grass seed mixturesto divot holes in lawns. The device as taught by Spring, however,requires that it be constantly held and is intended for use byprofessional lawn maintenance people. Furthermore, the Spring device islimited in that it requires a hand grip activation with linkages to anend-flap attachment, the end-flap attachment allowing passage of thesand and seed mixtures to the divots. The end-flap arrangement taught bySpring is prone to spilling the sand and seed mixtures beyond the divotsdue to a lack of channelization of the sand and seed mixtures.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PARTICULAR EMBODIMENTS

Figures described below illustrate particular embodiments for a lawnrepair device and system. Embodiments include lawn repair devices thatdeliver confined seed and sand mixtures to lawn divots by tiltactivation or piston assist devices that do not require tilt activation.The lawn repair devices, through either tilt activation or pistonassist, cause the interposing of an aperture beneath a reservoircontaining a sand and seed mixture. The sand and seed mixture thenpasses through the aperture and out a channel that aims and confines thesand and seed mixture to fill a user-selected divot. The system includesa storage chamber configured to charge the reservoir of the lawn repairdevice with initial and replacement seed and sand mixture lots.

Alternate embodiments include a self-standing lawn repair device thathas a tilt-activated trigger to dispense sand and seed mixtures in aconfined stream to a divot. The lawn repair device includes a curvedsliding shutter aperture that is normally spring-loaded shut in theun-deployed or at-rest state. When the device is tilted, a trigger orplunger is activated and places an aperture beneath a sand and seedreservoir to permit passing of the sand and seed mixtures. The sand andseed mixture transfers through a collimating block, through the apertureand into a channel downstream from the collimating block and aperture.With the collimating block and the channel, the sand and seed mixturesretain a column-like or stream configuration so that a precise aimingand accurate dispensing of the sand and seed mixtures is permitted.

The tilt activation includes a slidable leg that is pivotably engagedwith a shutter aperture curve plate, whereupon tilting the slidable legmoves and that movement in turn causes the spring-loaded shutteraperture curve plate to move beneath the reservoir. An aperture is thenplaced beneath the reservoir and sand and seed mixtures transfer throughthe aperture. Channelization of the sand and seed mixtures is achievedby the aperture that has a link to develop an initial channel strain,and further more the channel screen is maintained by a channeldownstream from the aperture that aims the channelized sand and seedstream into the divots. The amount of channelized sand and seed streamthat is delivered to the divots is controlled by the length of time thetrigger is maintained in an engaged state.

FIGS. 1-8 illustrate several embodiments of the lawn repair device thatdelivers focused streams of seed and sand mixtures via tilt activation.FIGS. 9-11 illustrate alternate embodiments activated by power sources.The power sources include gas pneumatic, hydro pressure, electric motorassist units or any other appropriate power source fitted to theembodiments illustrated in FIGS. 1-8. FIG. 12 illustrates incross-section details of the collimating block and aperture plate of theaforementioned embodiments of the lawn repair device. FIGS. 13-15illustrate an embodiment of a fill hopper used to charge the reservoirsof the lawn repair devices of FIGS. 1-11 with seed and sand or otherlawn repair or maintenance materials. The illustrative embodiments ofthe lawn repair device and fill hopper may be made of molded plastic,fiberglass, metal materials, or any combination thereof.

FIG. 1 is an isometric view depicting an embodiment of the lawn repairdevice in an at-rest or un-deployed position. The lawn repair device 10includes a reservoir 12, the reservoir 12 being substantiallycylindrical and able to contain a sand and seed mixture. The shape,length and diameter of the reservoir 12 may be varied to hold differentvolumes of sand and seed mixtures. In this illustration the outside ofthe reservoir 12 includes a scale 12A having the numbers 6, 9, 12, 15,18, 21, and 24. The scale numbers represent inches or other equivalentdimensions for estimating the quantity of sand and seed mixtures presentin the reservoir 12. Attached to the reservoir 12 is a handle 13. Thereservoir 12 is attached to a funnel 14 via a bolt 14A or similarrivets. The funnel 14 is sealed to a channel 16 that in turn is attachedto a three-leg support comprising two support legs 22 and a leverassembly 30. The support legs 22 may be attached to the funnel 14, asillustrated, the reservoir 12, or the channel 16. The attachment of thesupport legs 22 may be by spot welding, rivets, screws, bolts, or otherfasteners. The channel 16 includes a slot 18 located on opposite sidesof the channel 16.

The channel 16 has a substantially rectangular or square configuration,though it may be cylindrically shaped. Disposed approximately oppositeto the attachment points of the support legs 22 is a lever assembly 30.The lever assembly 30 includes a foot pad 36, a first hinge 38, a secondhinge 39, a plate 40 having an aperture 42 that slidably fits withinslot 18, and a spring 50 that engages against the lever assembly 30 andthe side exterior of the channel 16. As illustrated, the plate 40 iscurved and slidably moves within the slot 18. In other lawn repairdevice embodiments the plate 40 may be flat. The lever assembly 30reversibly articulates about the first hinge 38 attached to the exteriorof channel 16. The second hinge 39 is interposed between lever assembly30 and the curved aperture plate 40. The curved aperture plate 40 mayinclude stops, not shown, to prevent the plate 40 from being expelledfrom the slot 18 or to regulate the penetration depth of the aperture 42within the interior space of the channel 16. The coil spring 50 providestension such that the lawn repair device 10 is normally in an at-rest orstowed status in which the foot pad 36 is positioned as the third tripodleg together with support legs 22 and maintains the reservoir 12 in asubstantially vertical orientation and self-standing. The spring 50 islocated near the top of the lever assembly 30, and the first hinge 38 islocated near the bottom of the lever assembly. Pivoting occurs about thefirst hinge 38 and spring return from the top via the coil 50. In theself-standing status, the aperture 42 is externally disposed to thechannel 16. The at-rest status of the lawn repair device 10 is such thatthe curved aperture plate establishes a sealed block beneath the funnel14 such that sand and seed mixtures in the reservoir 12 do not pass intothe channel 16. The at-rest status of the lawn repair device 10 is suchthat the lawn repair device 10 is self-standing via the support stand20. As shown in the at-rest status condition of the FIG. 1, the secondstop is engaged against the exterior side of the channel 16 above theattachment locations of the support legs 22.

Sand and seed or other lawn repairmaterials stored within the chamber defined by the walls 101 and bottom102 is released from the opening created by the upward movement of thedoor 106. Repair materials transiting the opening of the door 106 flowalong the spillway 114 and into the reservoir 12 of devices 10 or 10A-E.

FIG. 14 is a bottom isometric view of the fill hopper 100. Theconfluence of the funnel shaped bottom 102 with the door 104 is moreclearly seen.

FIG. 15 is an internal top isometric view of the fill hopper 100. Again,the confluence of the funnel shaped bottom 102 abutting the door 104 ismore clearly seen.

Typical dimensions for aforementioned lawn repair devices 10 and 10A-E,though not restricted to the typical dimensions, include the reservoir12 having a length of approximately 24 inches and an internal diameterof approximately 5 inches. The internal diameter of approximately 5inches allows an approximate filling of eighty golf course divots perfoot of seed and sand mixtures contained in the reservoir 12. The mouthof the funnel 14 that mates with the cylinder 12 is approximately 5inches, then converges to a rectangular configuration having a 2 inch by2 inch square shape when viewed from the side. The channel 16 mates withthe converged section of the funnel, and similarly has a 2-inch by2-inch configuration when viewed from the bottom side. The length of thechannel 16 is approximately 12 inches. Approximately 2 inches below thefunnel 14 is the slot 18 located on opposing sides of the channel 16.The slot 18 is approximately 1.75 inches wide. The aperture plate 40 isslightly less than 1.75 inches and slidably oscillates between theat-rest or blocked position and the aperture-deployed position. Theaperture plate 40 is slightly curved or arched to maintain a sealagainst the internal walls of the channel 16 so that sand and seedmixtures do not leak from the reservoir 12 when the devices 10-10E arein the self-standing, at-rest position. The aperture 42 of the apertureplate 40 has a diameter of approximately ⅞ inches. The collimating block60 and the collimating channel 62 may have lengths shorter or greaterthan 2 inches.

FIG. 16 is a perspective view of an embodiment of a lawn repair deviceequipped with a hand crank to operate an internally located pulverizingdevice or clod disrupter 148. The clod disrupter 148 or rotatablydisrupts or breaks apart seed and soil clods to sizes sufficient totransit the collimating channel. The clod disrupter 148, shown in theinset, is rotatable by a hand crank 150. The hand crank 150 is shownattached through an upper chamber 140 via bearing orifice 120. The upperchamber 140 extends above the aperture plate 40 and beneath the funnel14. Sand and/or soil-based seed mixtures having an agglomerated orclod-like configuration are funneled to the entry area of thecollimating channel 16 where the clod disrupter is located. The incomingclod-like seed mixtures are chopped up or disrupted into smallerconfigurations by movement of the hand crank 150 that causes the cloddisrupter 148 to rotate the attached blades and provide a pulverizingmechanism or grinding action to particularize clumps of seed and sandmixture prior to reaching the aperture 42.

FIG. 17 illustrates a configuration of the internally disposed cloddisrupter 148 operated by the hand crank 150. The clod disrupter 148,shown in the inset, may be a rotatable blade assembly, a rotatablepropeller, or a helical shaped grinder that disrupts or chops up orparticulates larger sand and seed clumps to smaller forms. In thisparticular embodiment, continuous with the handle crank 150 is rotatableaxle 152, having chopper blades 154 attached with the axle 152. Rotationof the hand crank 150 rotates the axle 152 and in turn rotates thechopper blades 154 to provide pulverizing action to incoming seed andsand clumps. The axle 152 is secured by c-clip 180 engaged against theouter surface of the upper chamber 140. Seed and sand clods too large toenter the collimating channel 62 are chopped up until small enough forpassage through the collimating channel 62, the aperture 42, and thenthrough the channel 16.

While the preferred embodiment of the invention has been illustrated anddescribed, as noted above, many changes can be made without departingfrom the spirit and scope of the invention. For example, the cylinder 12of funnel 14 and the channel 16 of the lawn repair device 10 may be madeout of multiple materials including metal and plastics or fiberglass. Inparticular, the reservoir 12, the funnel 14, and the channel 16 may beunitary construction made from thermo-setting plastics. Moreover, thehandle 13 need not be a single cylinder-type handle. It may take theform of a suitcase-like handle that is mounted more in the centerposition of the cylinder 12 or on the other side of the cylinder 12 sothat the lawn repair device may be more readily grasped on each side ofthe cylinder 12. The open end of the cylinder may also be fitted with alid. Moreover, the embodiments described for the lawn repair device isnot limited to delivering lawn maintenance materials. For example, theembodiments of the aforementioned lawn repair device may be used fordelivery of other fluidized materials for purposes other than lawnrepair. Other fluidized materials deliverable by the lawn repair devicesinclude agricultural supplies for development of plant crops, gravelsupplies for path maintenance, chalk for playfield markings, or roadmaterials for road maintenance. In conjunction with these other uses forthe lawn repair devices, the hopper may similarly be used for fillingthe reservoirs of the lawn repair devices with fluidized materials otherthan lawn maintenance materials.
